This paper surveys a long term project, aimed at providing a general methodology for building up and maintaining an expert system oriented to Pattern Recognition problems. The methodology makes use of an integrated set of modules, performing different functions but sharing a common knowledge representation scheme. In particular, a learning module allows to acquire the knowledge automatically from a set of examples and another module performs sophisticated reasoning, on the basis of the available knowledge, during the recognition phase.

The most important fact brought out by a review of the present position of our knowledge of mineral metabolism and the mineral requirements in the dairy cow is, that, in spite of the amount of work which has been done on the subject, our information is exceedingly scanty. We know that deficiency of calcium or phosphorus may affect rate of growth, milk yield, breeding capacity, and in all probability susceptibility to certain diseases. We know also that even on what are counted good rations, depletion of the tissues, especially of calcium, in heavy milking cows during lactation is common. In some districts deficiency of iodine causes pathological conditions, and it is common knowledge based on practical observations that even on pasture there is liable to be a deficiency of chlorine. With regard to the possibility of deficiencies of other mineral elements and the effect of such deficiencies on the health and milk production of cows, we have not yet even begun to accumulate knowledge. It is thus impossible to make a final pronouncement with regard to any of the main problems. We need many more data on the metabolism of minerals in the lactating animal and on feeding experiments of long duration with rations of different mineral content. Such information as we have, however, suggests that the subject is one of great potential practical importance, and that if the necessary information were available it might be applied to the more economical production of milk, both by increasing milk yield and by reducing mortality from disease.With regard to the information we do possess, much of it is not immediately applicable in practice because the data have been accumulated with diets and under conditions which have no parallel in practice. The following conclusions sum up in a general way the practical bearing of our present knowledge.

The paper deals with the importance of common knowledge based on shared memory for the character of social cooperation. The findings are based on the background of Serbian experience with dealing with the past. The stabilization of a common stock of knowledge is valuable for establishing sustainable patterns of cooperation. The nexus between shared knowledge and different modalities of action is elaborated. Fearful and trustful actions are taken as basic modalities. Both are concerned with uncertainty over time and coping with the freedom of others as independent agents, but they evoke different expectations concerning the prospects of possible cooperation. The common assumptions of mutual expectations are crucial for the choice of cooperative strategy. Trustful cooperation is based on relying on others, while fearful action is based on an apprehension of threat. A “history of play” informs parties on mutual expectations. The irreducibility of shared memories shows that institutional incentives and signals are not able to stabilize shared knowledge on mutual expectations. The paper suggests that different conceptualizations are linked to different modalities of action and that rebuilding damaged relations requires shared reconstruction of a history of mutual relations. The thesis relies on a substantive argument about the particularity of common knowledge and a general argument based on the formal structure of social cooperation.

Some claim that consent requires common knowledge. For a doctor to obtain consent, a doctor must know that her patient has given her permission to perform surgery, and her patient must know the doctor knows that he has given this permission. Some claim that such common knowledge requires communication, and so consent requires communication: the patient must tell the doctor he consents for both to know consent took place, and for both to know the other knows consent took place. I first defend the claim that consent requires common knowledge, responding to recent objections. I then argue that, though consent requires common knowledge, it does not always require communication. It does not require communication when the agent obtaining consent can infer common knowledge based on non-behavioral facts about the world.

In every system of law there exist formalized rules of evidence, according to which facts have to be proven.A party in court may be required by his opponent to prove all the facts on which he desires to rely.Yet there must be a limit to the legal uncertainty of an endless chain of facts for which, otherwise, an equally endless chain of proofs might be demanded.Judges have a proper and powerful way to prevent superfluous debates as to the existence of what they deem to be generally known, or to have been already sufficiently established in a number of previous cases. Such facts can be declared to have become “public”, “judicial” or “common knowledge”.A fact so declared may, actually, be of a very complicated nature, such as a generally accepted scientific theory. The danger is, that no scientific theory is completely static, and widely accepted theories may, with justification be undermined by newer and more refined insights, but it usually takes some time until the new—and perhaps better—theory becomes generally accepted.For that reason, theories which are in a flux, or are being competently questioned, cannot be easily declared to have been solved one way or the other. Predilection towards a particularly emphasized conception to such extent as to declare that conception not merely preferred, but “public knowledge” may foreclose for a considerable time the prevalence of better conceptions.

Summary Objectives: Dentistry is a discipline with two properties that pose a serious challenge to knowledge based decision support: (1) It has to integrate six sub-disciplines ranging from conservative measures to invasive disciplines, such as implantology; (2) A plan may have to cover a complex treatment often lasting one year or more. It is the aim of the AIDA-project1 to set up a planning strategy that is suited to incorporate all dental peculiarities in one methodology. Methods: Generic tasks, that can be assigned to individual persons involved in dental treatment, have been designed with the help of KADS. They have been integrated into a planning super-structure for the planning of all dental solution alternatives, that can principally be applied on the basis of the given patient status. Results: Besides an evaluation of the implemented planning system itself, it has been evaluated how well the development is supported by (1) knowledge-engineering methods and (2) object-oriented methods. Conclusion: Common knowledge-based tools are not powerful enough for the planning of complex dental constructions. Therefore, a solution combining object-oriented and knowledge-based methods is proposed.
